The Seton Hall Pirates and South Florida Bulls linger closer to the dark side of the bubble, however, and likely need wins to feel good about their tournament chances. That's particularly true for South Florida, which remains light on quality wins. Beating the Villanova Wildcats (RPI 104) would not help in that regard. The Bulls will need to top the Notre Dame Irish in the Big East quarterfinals to feel secure about their Selection Sunday status.

Here's how the S-Curve shapes up on before Wednesday afternoon's action starts.

The S-Curve

This is where teams would fall if Selection Sunday were today. Remember, the curve flows left to right, then right to left, then back again as you read down the chart. Teams with an asterisk currently lead their conferences and project to receive automatic bids, per the rules of bracketology. While Michigan State, Ohio State and Michigan tied for the Big Ten regular-season title, the asterisk goes to the Spartans as they are the highest of the three teams on the S-Curve. Teams with an asterisk in bold have won their conference tournaments and clinched auto-bids.
